Preparation and Ferroelectric Properties of Lead-Free Bi_0.5Na_0.5TiO₃-BaTiO₃ Ceramics Synthesized with Citrate Method

Abstract:

Lead-free (1-x)Bi_0.5Na_0.5TiO₃-xBaTiO₃ (BNT-xBT) nano-powders synthesized by a modified citrate method and the sintered ceramics were characterized using various techniques. The r_{Subscript text}esults indicated that all the BNT-xBT samples were homogeneous with a pure perovskite crystal structure. It is found BNT-0.1BT exhibit_{Subscript text}s the best ferroelectric properties. BNT-0.0_{Subscript text}6BT has excellent performance in thermo-electrical energy conversion.
